Dr. Neel Kanth Kundu

Starting 2020, 5G services have been rolled out in various parts of the world. Now it is the right time to start investigating the new use cases and technologies for the next generation 6G communication technology for 2030 and beyond. This talk will discuss the various use cases and the required technologies in future 6G networks. This talk will discuss the various applications of quantum information technology in 6G Networks with a focus on quantum secure data transmission in 6G. Quantum key distribution (QKD) protocol can be used to distribute quantum secure keys between two legitimate users whose security is guaranteed by the laws of quantum physics. This talk will discuss continuous-variable QKD (CV-QKD), which can be implemented by using coherent laser sources and homodyne/ heterodyne detectors, making it easier to integrate into future 6G telecommunication networks. The talk will introduce the CV-QKD protocol and basic Gaussian quantum information theory tools required for the security analysis of CV-QKD. This talk will also present a multiple-input multiple-output (MIMO) transmission scheme for a CV-QKD system operating at THz frequencies. The talk will also present the latest QKD standardization activities taking place in the industry. Finally, the talk will discuss the practical challenges that need to be overcome for the deployment of QKD in 6G and beyond networks.

Biography:

Neel Kanth Kundu received the B.Tech. degree in electrical engineering with a specialization in communication systems and networking from the Indian Institute of Technology Delhi in 2018, and the Ph.D. degree in electronic and computer engineering (ECE) with a concentration in scientific computation from the Hong Kong University of Science and Technology (HKUST) in 2022. Since Oct’23, he has been with the Centre for Applied Research in Electronics, Indian Institute of Technology Delhi as an Assistant Professor. From Feb’23 to Oct’23 he was a postdoctoral research fellow with the Department of Electrical and Electronic Engineering at the University of Melbourne, Australia and from Sep’23 to Jan’24 he was a postdoctoral research associate with the department of ECE, HKUST in Hong Kong. His research interests include signal processing for 6G wireless communications, quantum communications, and quantum information processing.

Dr. Kundu is a recipient of DST INSPIRE faculty fellowship, the Hong Kong Ph.D. Fellowship, Overseas Research Award, HKUST RedBird Academic Excellence Award, and Hong Kong Telecommunication Institute of Information Technology Post-Graduate Excellence Scholarship. He was one of the winners of the 3 Minute Research Video Contest at the Global Young Scientists Summit 21 organized by National Research Foundation, Government of Singapore.
